You need to decide if you stay or go, if you stay learn the basic language.
There are bowling alleys in Portugal, I know of one in Lisbon and Algrave.
American football is not popular here but once he begins school he can play soccer (European football) and go to soccer games.

My son came here at five years of age went to school, made life long friends and at the moment is working in the computer field. Life is what you make of it, no one is going hand anything to you which ever country you live in.
